Sheila Singh

Singh graduated from McGill University in 1994 with a bachelor's degree in neurobiology and molecular genetics, and from McMaster University with an MD in 1997. She subsequently trained in neurosurgery at the University of Toronto from 1997-2007 and completed a PhD in the Surgeon Scientist Program (SSP) at McMaster University.[2] In 2006, Singh became certified in neurosurgery by The Royal College of Physicians and Surgeons of Canada (RCPSC) and then did a fellowship in pediatric neurosurgery at SickKids from 2006-2007.[2]

She has been recognized by invitations to serve as a grant reviewer for the NIH and CIHR. She has served as a brain tumor expert reviewer for the Pediatric Provincial Oncology Plan and the Pediatric Oncology Group of Ontario. She was a member of the Stem Cell Network AGM Steering Committee of the 2012 Till and McCulloch Meeting. She is active in the European Society for Medical Oncology and is on the editorial boards of Acta Neuropathologica Communications and of Current Pathobiology Reports. She is also a scientific advisor to Arch Biopartners of Toronto.

In 2017, she was named to the Royal Society of Canada's College of New Scholars, Artists, and Scientists.[4] In 2017, she was also made a University Scholar by the President of McMaster University.[2]

While in medical school, Singh encountered two five-year-old boys with brain tumors, both named Christopher. They were treated with the best current therapies of the time, however one flourished and the other died. This left her questioning the outcome, sparking her interest in cancer research.[1]

The Sheila Singh Lab research program consists of a team of around 20 undergraduate, graduate and postdoctoral students with Singh as the principal investigator (PI) working at the Stem Cell and Cancer Research Institute in Hamilton.[1][2] Sheila is the first woman to lead such a program as PI and the first scientist from McMaster to do so.[2]

Singh discovered an abnormal stem cell, the brain tumor initiating cell (BTIC), which may be the key to understanding the formation of brain tumors.[1]

The driving idea in Singh's research is the idea that only a small population of cancer stem cells in a brain tumor are capable of propagating, thus focusing on the rare tumor stem cell and not every cell in the tumor. So Singh's lab focuses on therapies that target the BTIC in hopes that it could better halt the propagation of tumors. Singh's lab focuses on understanding the molecular mechanisms that govern BTIC self-renewal, building upon cell culture techniques used for isolating normal neural stem cells (NSC), applying them to brain tumors and developing a xenograft model to study BTIC activity.[1]

Singh's lab currently studies the regulation of BTIC signaling pathways in medulloblastomas (MB), glioblastomas (GBM), and brain metastases (BM).[1] Singh's lab found that patients that have a higher proportion of BTICs may have shorter survival and a worse prognosis, offering insight into patient prognosis and forming the basis for medical therapies aimed at the BTIC.[1]

On her inspiration for her research, Singh said, "You see a lot of things in pediatric neurosurgery and all of them — good and bad — inspire my research. And every person who works with me has a direct connection to the ‘Why?’ of research. Very often patients and their families will come for a tour of the lab and my people get to meet them. There is a real connection. People in my lab work twice as hard because they have that direct motivation. I began my research career inspired to understand why one brain tumor patient with flourished, while the other with the same disease died. Now, my research program is dedicated to applying a developmental neurobiology approach to the study of human brain tumors. We do this by developing pre-clinical models that recapitulate the human disease. Our ultimate goal is to generate novel, targeted and effective therapies for brain tumor patients."[1]

Singh's lab is supported by the Stem Cell and Cancer Research Institute (SCC-RI), Hamilton Health Sciences, McMaster University, the Brain Tumour Foundation of Canada, Team Kelsey: Brain Tumour Awareness, the Ontario Institute for Cancer Research (OICR), the Brain Canada Foundation, BoxRun, Canadian Cancer Society, American Brain Tumor Association, NSERC CRSNG, Mitacs, CIHR IRSC, Stem Cell Network, The Terry Fox Research Institute (TFRI), Cancer Research Society, Jace Wars, BioCanRx, National Brain Tumor Society, Canada Foundation for Innovation, and Canada Research Chairs.[1]

Singh and her research colleagues won a Terry Fox New Frontiers Program Project Grant from the TFRI in 2016, worth $2.75M over five years.[2]
